New Concept of Hybrid Fiber Reinforced Shotcrete in Reparation Engineering
Based on the analysis of the advantages and disadvantages of single-doped fiber shotcrete ,and the research and application of fiber shotcrete in domestic and international.This article bring forth a new concept of hybrid fiber reinforced shotcrete that includes steel fiber (SF), high-elastic fiber polyvinyl alcohol fiber (PVAF) and low-elastic polypropylene fiber (PPF), which would improve concretes resistance, tensile strength, ductility and other physical and mechanical properties. On the basis of the combination of domestic and international fiber research and application of single fiber sprayed concrete, according to binary or ternary hybrid fiber reinforced concrete jet feasibility pitch-based fibers theory, both economic and performance should be taking into account, steel fiber (SF), PVA fiber and low-elastic polypropylene fiber (PPF) could add to the shotcrete by considerable mix design and orthogonal design .In order to develop the method of hybrid fiber reinforced shotcrete rapidly and make widely use of the hybrid fiber reinforced shotcrete in reparation and reinforcement Engineering , spray technology and construction process should be developed as well as quality control measures and construction cost control.
